PRSalpha ATC 4' x 8' with 5hp HSD spindle
Starting at: $33,870

The PRSalpha ATC is the affordable CNC solution that delivers high performance, high volume, speed, and reliable power. Just like our PRSalpha tool, it provides full-production performance in the digital fabrication of wood, plastic, aluminum, and other materials, but the PRSalpha ATC has the added capability of an Automatic Tool Changer. An ATC reduces production time by automatically changing cutters between tool paths, thus eliminating the need for the CNC operator to change and zero tools individually. This allows the PRSalpha ATC to do the full job, even when different tooling is required to make different types of cuts – like cabinets and furniture – or where different bits are needed for roughing and finishing passes – like signs and complex 3D carvings. A machine equipped with an ATC can perform operations normally done on other pieces of equipment, eliminating the need for additional machines in the shop.

Available in traditional shop-size and larger, PRSalpha ATC tools are available with 8” or 14” Z travel. In addition to our standard size tools, we can build your tool to any dimension up to 10’ by 30’ and with plunge depths up to 24 inches. Other customizable components are available, including an HSD 10 HP Spindle.

Our most popular table sizes:

4’ x 4’, 4’ x 8’, 4’ x 10’, 5’ x 10’, 5’ x 12’

Powered by an HSD ES915 5hp spindle.

While there are endless possibilities of what you can do with the ShopBot PRSalpha, here are a few examples of areas where people are putting their CNC tool to use:

Cabinet Making

With CNC, cabinetmakers can drill shelf pin holes, cut rabbets and dados, and profile-cut a completed panel. The operator only needs to handle the full sheet once to load the machine, and then remove the perfectly cut parts when complete.

Theaters and Museums

Realize your team’s aesthetic vision and go quickly from hand drawing to CAD design to full-size scenery panels. Complexity is easily incorporated when using CNC, so you can execute all kinds of ideas—including creating components in 3D.

Sign Making

Sign makers are using CNC for 3D carving, V-bit carving, profile contouring, fluting, and engraving. It also provides them with the opportunity to cut their own channel letter components, frames, posts, and borders in-house.

Furniture

High-volume furniture and millwork companies, as well as novice and master craftsmen, are embracing CNC technology. Craftsmen are quickly realizing that the CNC process doesn’t jeopardize their pieces' authenticity; it only adds to quality and uniqueness of the finished product.
